Description

  The present invention relates to a marking liquid ejection and attachment device that ejects and attaches marking liquid as evidence to a criminal's clothes or shoes when a crime occurs.

Conventionally, a method using a color liquid capsule ball (color ball) which is difficult to fall is known. This is evidenced by the adhering color liquid that was thrown to the criminal or the vehicle being used for the escape when the crime occurred, collided and burst.
There is also known a fire extinguisher type crime prevention device that injects a special liquid from a container filled with the special liquid and a compression air through a nozzle (for example, see Cited Document 1 and Cited Document 2).

Further, a technique is known in which a special liquid is filled into a cylinder, and a piston is pushed out by a spring to inject the special liquid from a nozzle to a criminal (for example, refer to cited document 3).
There is also known a crime prevention system that senses human body temperature in a non-contact manner, operates a liquid ejecting device in response to the signal, and injects and adheres liquid to a target person's clothes or the like (see, for example, cited document 4).

On the other hand, the liquid has a high risk of counterattack because it attaches color and odor. In addition, cleaning up is a problem in terms of quantity.

Moreover, about the discharge position, all employ | adopted the method of projecting on clothes, Naturally it will be noticed by the criminal, and the danger of a counterattack is included.
In addition, in the method using a color ball and the inventions described in the cited documents 1 to 3, the crime can be concealed by changing clothes, washing, or discarding after the crime, and lacks certainty. .

From the above situation, it is very difficult to catch a criminal after the crime, especially when a burglar invades a convenience store or the like.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 4 show a marking liquid discharge attachment apparatus A according to an embodiment of the present invention (corresponding to claims 1 and 3).
The marking liquid discharge attachment apparatus A according to the present embodiment has a substantially rectangular case body 1 composed of covers 2 and 3. After the cover 3 is placed on the cover 2, the cover 2, 3 has screw rods (not shown) in the holes 3 b provided in the four corners of the cover 3 on the seat 2 a with screw holes provided in the four corners of the cover 2. It is designed to be integrated by screwing. The case body 1 is connected to an accumulator-type pressure vessel 4 enclosing the marking liquid M and a fluid supply / discharge port of the accumulator-type pressure vessel 4, and discharges the marking liquid M in the accumulator-type pressure vessel 4 to the outside. A solenoid valve device 5 having a discharge nozzle 6, a control circuit device 7 for controlling the drive of the solenoid valve device 5, a battery 8 for supplying power to the drive device and the control circuit device 7 of the solenoid valve device 5, and the control circuit A switch device (not shown) for operating the electromagnetic valve device 5 through the device 7 is arranged. The accumulator-type pressure vessel 4 and the electromagnetic valve device 5 are positioned on the case body 1 via a stopper 9. The distal end of the discharge nozzle 6 of the electromagnetic valve device 5 is arranged to the outside through a hole 3 a formed in one surface of the case 3.

  The accumulator-type pressure vessel 4 includes a bag 4a in which a marking liquid M is sealed, a valve 4c mounted in a hollow connecting portion 4b connected to the bag 4a, and a spring 4d that normally biases the valve 4c in the valve closing direction. A mechanism 4e, a bag 4a and a valve mechanism 4e are built in, and the container body 4f is filled with compressed air 4g for pressurizing the bag 4a. Accordingly, the bag 4a is surrounded by the compressed air 4g, and is kept in a state where pressure is always applied inward, that is, a state where the balloon is pushed from the outside.

Here, the marking liquid M is a luminescent agent that reacts with an odor that humans do not understand, such as black light. The smell is what the police dog is tracking, and the luminescent agent can be tracked by the police officer.
As shown in FIGS. 2 and 3, the electromagnetic valve device 5 includes a valve body 10, a solenoid 11 attached to a side surface thereof, and a socket 12. A screw hole 10b is formed in the lower surface of the valve body 10, and the bottom side opens to a valve chamber 10c formed in the side surface, and a connection port 10a is formed through the center of the valve chamber 10c. A discharge nozzle 6 is press-fitted into the connection port 10a of the valve body 10 in order to discharge the marking liquid M made of a thin pipe thinly on a straight line. A two-way valve is configured between the open end of the connection port 10a of the valve body 10 and the tip of the plunger (movable iron core) 11a of the solenoid 11. As shown in FIG. 3, the solenoid 11 is always urged toward the connection port 10a by the spring 11b, and when energized, the plunger 11a is attracted against the spring force of the spring 11b, as shown in FIG. In this way, the marking liquid M in the accumulator pressure vessel 4 is supplied from the supply port 10d through the valve chamber 10c to the tip of the connection port 10a and the discharge nozzle 6 from the socket 12 toward the target. Then, the marking liquid M is ejected. Thus, the solenoid 11 operates the operation of supplying or stopping the marking liquid M to the discharge nozzle 6 by electromagnetic force. A seal ring 10e is mounted between the valve chamber 10c of the valve body 10 and the plunger 11a of the solenoid 11. The socket 12 has a connecting portion 12a screwed into the screw hole 10b of the valve body 10. A seal ring 13 such as an O-ring is mounted between the valve body 10 and the socket 12. The socket 12 includes an annular protrusion 12b that pushes down the tank valve 4c of the accumulator-type pressure vessel 4 on the opposite side of the connecting portion 12a. Further, the socket 12 includes a flange portion 12c on the lower side of the connection portion 12a in order to support the stopper 9.

Next, the operation of the marking liquid discharge attachment device A according to the present embodiment configured as described above will be described.
As shown in FIG. 2, the accumulator-type pressure vessel 4 is attached to the valve body 10 to which the solenoid 11 and the socket 12 are attached. At this time, as shown in FIG. 4, the plunger 11 a of the solenoid 11 abuts on the connection port 10 a of the valve chamber 10 c to block the flow path to the discharge nozzle 6. The marking liquid M is filled in a passage communicating from the accumulator-type pressure vessel 4 to the valve chamber 10C.

Thus, the accumulator type pressure vessel 4 assembled with the electromagnetic valve device 10 is arranged in the case body 1 as shown in FIG. A control device 7 and a battery 8 are arranged in the case body 1. The control device 7 is provided with a cord for contacting a switch device installed at a predetermined location.
When these integrations are completed, the cover 2 is covered with the cover 3, and both are fixed via a screw rod.

Thus, the assembly of the marking liquid ejection attachment device A according to the present embodiment is completed.
Next, a usage example of the marking liquid discharge attachment device A according to the present embodiment will be described.
FIG. 5 shows an example in which the marking liquid ejection attachment device A according to the present embodiment is installed at the foot of the counter 20. For example, when the employee 21 presses a switch device (not shown) installed at a position that is not visible from the inside of the counter 20, the marking liquid discharge attachment device A according to the present embodiment is operated, and the marking is performed from the discharge nozzle 6. The liquid M is discharged to the feet (near shoes and trouser ankles) of the criminal 22 who is the subject. At this time, in the electromagnetic valve device 5, the marking liquid filled in the passage communicating from the accumulator-type pressure vessel 4 side with the plunger 11a being sucked to the left side in FIG. 4, opening the connection port 10a of the valve chamber 10c. M is ejected from the discharge nozzle 6 to the outside. The solenoid valve device 5 is energized in pulses, and the marking liquid M also intermittently jumps out of the discharge nozzle 6 by a predetermined amount.

  FIG. 6 shows an example in which the marking liquid discharge attachment device A according to the present embodiment is installed at the foot near the entrance door 23. For example, when an employee presses a switch installed at a position invisible from the outside of the counter, it is discharged to the feet of the criminal 22 (in the vicinity of shoes and trouser ankles). Alternatively, when the switch is pressed by an employee, it is possible to sense the place where the criminal 22 approaches to escape from the door 23 after the crime, and to operate the marking liquid discharge attachment device A according to the present embodiment. Also in this case, in the electromagnetic valve device 5, the plunger 11a is sucked to the left side in FIG. 4, opens the connection port 10a of the valve chamber 10c, and fills the passage communicating from the accumulator pressure vessel 4 side. The liquid M is ejected from the discharge nozzle 6 to the outside. The solenoid valve device 5 is energized in pulses, and the marking liquid M also intermittently jumps out of the discharge nozzle 6 by a predetermined amount.

  As described above, the marking liquid discharge attachment apparatus A according to the present embodiment is unitized and built in the case 1. Therefore, the marking liquid discharge attachment apparatus A can be easily installed and can be opened and closed. It is possible to easily replace the cylinder of the pressure vessel 4 or the battery 8. Moreover, the marking liquid discharge attachment apparatus A which concerns on this embodiment can discharge the marking liquid M, and can make it adhere | attach without the criminal 22 noticing.

Moreover, the marking liquid discharge attachment apparatus A which concerns on this embodiment is installed in the place close | similar to a floor, and the effect can be heightened more by setting it as the position where marking liquid M can adhere to the criminal 22's ankle vicinity.
In addition, the marking liquid discharge attachment apparatus A according to the present embodiment can be disposed at a place where the criminal 22 stops such as an entrance / exit or in front of a counter, so that the marking liquid M can be reliably attached.

Moreover, since the marking liquid M is a luminescent agent that reacts with a scent that the person does not know and black light or the like, the police dog can track the odor after adhering without being noticed by the criminal 22, and the luminescent agent Can be tracked by police officers. Therefore, there is no fear of being washed away or discarded by the criminal 22, and it can be used effectively as evidence.
The marking liquid discharge attaching apparatus A according to the present embodiment can be attached at one place and several places, and can be increased or decreased depending on the situation.

As described above, since the marking liquid M is not noticed by the criminal 22, a minute amount can be repeatedly discharged from the discharge nozzle 6 of the electromagnetic valve device 5 in a state close to silence for a predetermined time. The discharge amount of one shot can be adjusted by the opening / closing speed of the electromagnetic valve device 5.
The marking liquid M is ejected linearly in a granular form, rather than in the form of a mist, in order to ensure that the marking liquid M adheres firmly to the target even at a specific distance. Further, the solenoid valve device 5 is required to move reliably even if it has not been operated for more than one year.

In order to fly the marking liquid M linearly, a discharge nozzle 6 is mounted at the discharge outlet, and a dedicated cylinder is used to discharge only the marking liquid M. A dedicated cylinder is one in which the liquid filled in the cylinder and the compressed gas are not mixed. Therefore, an accumulator-like structure is preferable.
For example, the fixed time is a time until the criminal 22 commits to escape. In order to avoid adhesion of the marking liquid M to people other than the criminal 22, it automatically stops after discharging for a certain time. Basically, when a crime is committed, a specific action is taken to activate a signal. The specific operation of the marking liquid ejection attachment device A according to the present embodiment is that the employee 21 manually pushes the switch.

In the above-described embodiment, the case where the switch device is connected by wire has been described. However, the present invention is not limited to this and can be wireless. In this case, a switch lead wire is not necessary. This eliminates the need for lead wire wiring and simplifies installation and eliminates the need to select a location.
For example, considering that the criminal escapes from the automatic door, the marking liquid M can be discharged at the timing when the automatic door is opened in conjunction with the sensor of the automatic door. Thereby, the marking liquid M can adhere to a criminal exactly. In addition, when attached to an unmanned device such as an ATM, by allowing the marking liquid M to be ejected in response to a vibration sensor or the like, the liquid can be attached to the criminal even without the person.

  Moreover, although the case where the battery was mounted as a power supply was demonstrated in the said embodiment, this invention is not restricted to this, It is good also as a connection apparatus (for example, AC adapter etc.) for connecting to an external power supply. In this case, it can be easily implemented by adding a rectifier or the like. Further, it is possible to connect to both of these batteries and an external power source, and this allows installation at an appropriate place (position).
